Basic information required to conserve wild tigers Panthera tigris is lacking for the Bangladesh Sundarbans. The objectives of this study were therefore to estimate tiger home range size and obtain information on movement. Two adult female tigers were captured in the south-east of the Sundarbans and fitted with global positioning system collars. Mean home range sizes for the two tigers estimated with 95% minimum convex polygon and fixed kernel methods were 12.3 and 14.2 km2, respectively. A mean female home range size of 14.2 km2 would indicate a density for the south-east Sundarbans of seven adult females per 100 km2. The maximum distance moved by a tiger in 1 day was 11.3 km. Although preliminary these home range estimates indicate that the Sundarbans of Bangladesh has good quality tiger habitat relative to other tiger landscapes, highlighting the value of this mangrove ecosystem for the survival of this Endangered species.
